<p>Provided are a charge-transporting varnish, a charge-transporting thin film, and an organic electroluminescent (EL) device, which are capable of implementing superior luminance characteristics when applied to the hole injection layer of an organic EL device. A charge-transporting varnish comprises: a charge-transporting material consisting of thiophene derivatives represented by formula 1, dopants, and organic solvents. In the formulas from 2-1 to 2-10, R^1 to R^36, independently, indicate hydrogen, halogen, nitro group, cyano group, aldehyde group, hydroxyl group, thiol group, carboxylic acid group, alkyl group, alkenyl group, alkynyl group, aryl group, -C(O)Y^1 group, -OY^2 group, -SY^3 group, -C(O)OY^4 group, -OC(O)Y^5 group, -C(O)NHY^6 group, or -C(O)NY^7Y^8 group.</p> |
